Research on the Matching of Fastener Stiffness Based on Wheel‐Rail Contact Mechanism for Prevention of Rail Corrugation [PDF]
Mathematical Problems in Engineering, 2017 Laying shock absorber fasteners is one of the effective countermeasures used to reduce the ground vibration induced from urban rail transit. However, this kind of fasteners could cause severe rail corrugation. Based on the “wheel‐rail dynamic flexibility difference” mechanism, the optimization and further research of fastener stiffness were performed ...
